Hello,
I have c++ variables in a class that are marked as BlueprintReadWrite. Now when I use these variables in blueprint graph, add one more variable in c++ class later and hotreload I get following bug:
and message “Error This blueprint (self) is not a HOTRELOADED_MyDecal_1, therefore ’ Target ’ must have a connection.”
I have to replace every c++ variable in the graph to get it work again.
So I think new variable changes “ids” of all old variables and blueprint can not recognize them.
+1,
I’m seeing this as well. While restarting the editor fixes the issue, that defeats the purpose of hotreload!
Hey Footman-
This is a known issue (UE-11427) that has been fixed internally. This fix should be included in a future update to the engine.
Cheers
Has this been fixed for 4.8? Still experiencing it with 4.7.6. Restarting the engine after changing any code that affects a BP is pretty tedious.
Hey DG Gage-
I tested this in the current 4.8 preview 3 available and found it was fixed. I was able to add a new variable to the code and hot reload the project without the error to the blueprint.
